Hi! I just found this board on , ATxmega128a3u powered arduinos combined with an atmega328p. It have two DAC's, like the DUE, and run at 32MHz. it runs at 3.3v but combined with the 328p it looks like a great team! can't these two AVRs communicate via I2C or SPI, so the xmega handles the calculations, while the 328p stands for the output? I just ordered a board from ebay for 25$, so i'm excited to test it out! more info about this board can be found at http://obdiiworld.com
What do you guys thing about this board? why haven't the xmega been used before in an arduino?
